Pshhht easy. All you have to do is get people to retweet "One Direction has been caught #BurningHamsters for fun!", and then all of the sudden you will be met by hoards of preteen girls tweeting back "omg u r so jelous cuz thay faymous stap this #BurningHamsters stuf" or something of a similar level.

Edit: Notice that I used the word "preteen", they tend to be the most reactionary.
